Effect of Cooling Rate on Glass Transition Temperature and Enthalpy and Volume Relaxation of Polystyrene
Original language description
Cooling rate dependence of glass transition temperature was measured for PS using Mercury-in-Glass Dilatometry (MIG). The enthalpy (DSC apparatus) and volume relaxation (MIG) of PS were measured after cooling from equilibrium liquid state to relaxation temperature below Tg after cooling by different rate. Enthalpy and volume relaxation data were discussed in terms of Kohlrauch-Williams-Watt (KWW) and Tool-Narayanaswami-Moynihan (TNM) expressions. From enthalpy and volume relaxation data the ratio ?h/?vwas calculated giving 1.8 GPa, similar to the bulk modulus measured by direct compression.

Vliv rychlosti chlazení na teplotu skelného přechodu a entalpickou a objemovou relaxaci polystyrenu
Czech description
Vliv rychlosti chlazení byl měřen u PS za použití rtuťové dilatometrie a DSC. Data byla diskutována pomocí Kohlrauch-Williams-Wat and Tool-Narayanaswami-Moynihan rovnic. Entalpický/objemový poměr vychází 1.8GPa, podobný modulu měřeného přímým stlačením.
